For the past several years I have been using a custom sound as my alert sound. Now that i just "upgraded" to Leopard, the custom sound has been removed. I tried putting the small mp3 file back in the sounds folder like I have done ever since 10.2 but it doesn't work. Does anyone have any idea what is going on, and how I can get my custom sound back? It is frustrating, due to many other problems on top of this one if I didn't have to use bootcamp all the time I would go back to using 10.4.
